一、产品简介   Product Brief

       WR系列工业用隔爆、本安型防爆热电偶是一种温度传感器,在化学工业自控系统中应用极广,通过温度传感器,可将控制对象的温度参数变成电信号,传递给显示、记录和调节仪表,对系统实行检测、调节和控制。

        WR Series For industrial use Flameproof, Intrinsically safe type thermocouple Is a kind of temperature sensor, In the chemical industry in the automatic control system of wide application, Through the temperature sensor, Can put the control object The temperature parameter to electrical signal, Transferred to display, record and control instrument, On the system The implementation of inspection, regulation and control.

 

       在化工厂,生产现场常伴有各种易燃、易爆等化学气体、蒸汽,如果使用普通的热电偶非常不安全,极易引起环境气体爆炸。因此,在这些场合必须使用隔爆或本安型热电偶作温度传感器,本公司生产隔爆或本安型热电偶产品适用在EX dIICT1~dIICT6温度组别区间内具有爆炸气体危险的场所内。

       In the chemical plant, The production site is often accompanied by a variety of flammable, Explosive chemical gas, Steam, If using the ordinary thermocouple very unsafe, Extremely easy to cause environment gas explosion. Therefore, In these situations must use flameproof Or intrinsically safe type thermocouple as temperature sensor, The company production of Flameproof Or intrinsically safe type thermocouple products Applicable in EX dIICT1~dIICT6 Temperature group interval With explosive gases in dangerous places.

 

       本公司生产的隔爆或本安型防爆热电偶技术性能符合ZBN11002-2010工业热电偶技术条件和ZBY300-2010工业热电偶分度表及允许误差,同时产品均符合爆炸性环境用防爆电气设备通用要求GB3836.1~2010GB3836.2-2010标准,由仪器仪表防爆安全监督检验站对产品的图样、技术文件、样机进行专门审定和批准,并以给防爆合格证,隔爆热电偶合格证号:CNEx14.2076X

       The company production of Flameproof Or intrinsically safe type thermocouple Technical performance in line with ZBN11002-2010 Industrial thermocouple Technology conditions And ZBY300-2010 Industrial thermocouple indexing table And permissible error, At the same time product Accord with the used in explosive environment Explosion proof electrical equipment General requirements GB3836.1~2010GB3836.2-2010 Standard, By the national Explosion-proof instrument of safety supervision and inspection station On the product pattern, Technical documents, Prototype Special Examination and approval, And to give the explosion-proof certificate, Explosion proof thermocouple certificate no.: CNEx14.2076X

 

       本安型必须使用本安补偿导线,其分布参数控制范围:总电感量≤2mH,电容量≤0.06μ,同时使用关联设备安全栅,关联设备的选用按下原则,热电偶(必须是绝缘式)配二次仪表时,必须选用FB系列安全栅,安全栅的具体接线见具体产品的说明书。

       Intrinsically safe type thermocouple You must use the intrinsically safe compensation wire, The distributed parameter control range: The total inductance ≤2mHCapacitance≤0.06μAt the same time, the use of Associated equipment safety gate, The device context Selection Press the principle, Thermocouple(must be insulated type) With two instruments, Must be selected FB series of safety barrier, Safety grid Specific wiring See specific product specifications.

 

二、原理结构   The principle structure

       隔爆或本安热电偶与装配式热电偶的结构,原理基本相同,所区别的是,隔爆或本安型产品接线盒(外壳)在设计上采用防爆特殊结构,接线盒用高强度铝合金压铸而成,并具有足够的内部空间、壁厚和机械强度,橡胶密封圈的热稳定性均符合防爆标准。所以,当接线盒内部的爆炸性混合气体发生爆炸时,其内压不会破坏接线盒,而由此产生的热能不能向外扩散传爆。

       Flameproof Or intrinsically safe thermocouple And the assembly type thermocouple Structure, The same basic principles,The difference is, Flameproof Or intrinsically safe product Junction box (shell) In the design of the Explosion proof special structure, Wiring box for high strength aluminum alloy die-casting and, And has sufficient internal space, Wall thickness and mechanical strength, The rubber sealing ring Thermal stability Are in line with national standards for explosion proof. So, When the wiring inside the box Explosive gas mixture When the explosion, The inner pressure Will not damage the junction box, The resulting Heat energy can not be outward diffusion of detonation.

 

       由于产品采用上述防爆特殊结构,使产品完全符合使用在dIIBT4dIICT6ibBT4iaIICT6防爆类别范围内,只要用户严格遵守产品使用规则,产品就能达到可靠的防爆效果。

       Because the product uses The explosion-proof special structure, The product fully meets the use in dIIBT4 To dIICT6ibBT4iaIICT6 Explosion proof class scope, As long as the user Products in strict compliance with the rules of use, The product can achieve reliable Explosion proof effect.
